Works great for two full clips.
Fits two full nail clips. Metabo should make this the one that comes with nailers.

Great Upgrade
I am a General Contractor and frame regularly with my NR1890 cordless gun. Replaced the OEM short magazine with this one. Obviously the higher capacity is a big plus but this is also just a much better magazine all together. It's a metal body where the OEM is plastic. The nail follower is much smoother and more forgiving resulting in faster reloads. The release is much easier to operate and the spring on the follower much stronger. I've only used it a day so far but this was more than I expected. Metabo fixed all the fussy feed jams & difficulty to clear, difficulty reloading and failure to feed issues I had with the OE magazine the gun came with. Install directions could be a little better but if you take your time, you can swap this out on my NR1890 in about 15 minutes.

I really like it
My nail gun has been working great for a year now, so I decided to get the extended nail magazine. And it really works great so far I’ve been using it for about a month to get to strips and nails in. Works good.

Changes everything
Turns the gun into a machine I don’t know how I was framing with the stock magazine

Great Add On!
This should be installed from the factory. It does add a little weight, but significantly reduced nuisance reloading.

👍
Easy to install and works great. Makes the gun a little more heavy but worth it. It’s nice having the extra nail capacity, not having to stop and reload as often.

Magazine extender 21° metabo framing nailer
It looks like This exact model number it is not fully compatible with the new Metabo 21°framming cordless nailer the magazine extension right on the top end metal piece the attachment holes won't match to the ones on the nailer.. the middle bolt and mounting bracket extender also won't fit the 4 holes on it won't math the ones on the new metabo nailer and last the safety metal pin blocker have to be remove and head have to be relocated for the one comes on the nailer that have no mechanical function but use a magnetic sensor this magazine extender is design for metabo or may be hitachi models but not the newer models
